Fabrication and erection of gantry portals for route guidance signs above highways.
Fabrication, corrosion protection and erection of the portal steel structures for two general contractors.
Task
Gantry portals for road signs and route guidance boards above multi-lane highways — as subcontractor to Gülsan İnşaat and Todini Costruzioni Generali, general contractors of the State Road Service of Ukraine. Lattice crossbeams and posts spanning the whole carriageway and holding the signs under wind load had to be fabricated and erected on the road without closing it for long.
Solution
The portals were fabricated at our own works: lattice crossbeams and posts to shop drawings, embedded parts for the foundations, corrosion protection applied in the shop. The structures arrived on the road as finished sections, so that only bolted joints remained on site. The posts were set on the anchor bolts of the foundations, the crossbeam was lifted by crane and fixed to the posts; during the lift traffic was restricted only on the lanes the crane worked above. The main difficulty was logistics: crane operation, delivery of the crossbeam sections and the crew’s work had to be coordinated within a limited time on the road, so the sequence of lifts was planned in advance.
